We are newly retired couple, both 62s. We plan to visit Europe starting in mid-September. I've read many threads covering transportation as well as lodging and places to visit. I've compared cost for global pass and rental car for the same period. I decided to rent/lease a car through Renaultusa picking it up from Frankfurt and returning it in Paris. After 10 days in Paris, we'll catch the Eurostar to London. I decided to rent a car for convenience which also allows us to go places not covered by train routes. Also, the cost is comparable with global train pass. We'll equip ourselves with pocket-wifi or buy local sim with data plan. The idea is to stay in a city/town from 3 to 10 days and will not reserve lodging until couple days before arriving to the city. From Germany, we'll drive to Austria, Switzerland, Italy, Spain and finally to France. We plan to stay/visit one or more cities of each country. I've been to Germany/France once during my military time on a short trip only, my spouse never been.
We're well within the Schengen stay limit. The car, although it's a expensive, I think it's worth it given that it includes insurance and road service, plus it's a new car with built in gps and it can be driven to all the countries we'll visit.
If I have not covered any major aspect of the trip or anything that may make the trip more cost effective/convenient/pleasant, please share your thoughts.
